Protective spring connector 4 mm2 (yellow-green) ESP-HTE.4 003903192

Protective spring connector – reliable connection in electrical installations

The ETI Polam 4 mm² protective spring connector is an element used for safe and quick connection of protective conductors (PE) in electrical installations. Designed for mounting on a 35 mm DIN rail, it provides a solid and durable connection, minimizing the risk of short circuits and damage. Its green-yellow color makes it easy to identify the protective conductor, which is crucial for the safety of the entire system.

Design and application

The connector is made of high-quality thermoplastic material with flammability class V0, guaranteeing resistance to high temperatures and fire, meeting strict safety standards. The use of screw connections ensures a secure and reliable connection of solid and stranded wires with a cross-section from 1.5 mm² to 4 mm². Thanks to its compact dimensions (width 7.5 mm, height 43 mm), the connector is ideal for use in electrical switchboards with limited space. The PEN function allows connection of the equipotential bonding conductor.

Advantages and benefits

• Quick installation: spring clamps allow for quick connection of wires without the use of specialized tools – saving time for both the installer and the end user.
• Safety: high quality materials and construction ensure a reliable connection and effective protection against short circuits and electric shock.
• Versatility: the ability to connect solid and stranded wires with a cross-section from 1.5 to 4 mm² makes the connector compatible with various types of installations.
• Durability: resistance to weather conditions (operating temperature range from -40°C to +100°C) guarantees long-lasting and trouble-free operation.
• Readability: the green-yellow color makes it easier to identify the protective conductor, which increases safety during work and maintenance of the installation.
• Compact dimensions: allow for mounting in tight spaces of electrical switchboards.
